To all whom it may concern:

Be it known that I, JAMES MEADE, a citizen of the United States, residing at Stoughton", in the county of Norfolk and State of Massachusetts, have invented new and useful Improvempnt in Methods of Coating vy'liich t Fabrics, of he following is a specification.

My invention concerns the coating of fabrics with waterproof substances, and particularly relates to doubled goods in whith the coating is between plural layers of the fabric: j

It consists in an improved method whereby a sufficient thickness of the Waterproofbeneath its vertically adjustable gage-knife the means which first presses the or spreading member 11. The latter is so adj usted as to apply to the fabric a compare atively light or shallow coating of a suitable waterproof substance, which is placed in a plastioacpndition upon the fabric over the bed-roll and against the knife. The fabric thus. coated. then travels on over drying means, conveniently a series of steam coils 12 arranged in an upwardly inclined plane, about aflroll l3 driven at the proper speed to advance'lthe goods, and then is directed along a path of some length by idle rolls 14, 17, and. driven rolls l5, 16 to the bed-roll l8 and knife 19 of a second spreader D. By the time this element is reach ed, the solvent in the initial coating has sufiiciently evaporated. This coating, on account of its light bulk or shallow character, so fills the surface of the..-fabric, without passing through to the other side, that said fabric is in condition to' safely heavy or 'deep coating, applied at the spreader Dfand provided for by the proper adjustment; of the gage-knife. At this stage thesecond layer of fabric Y comes from the source of supply B, and is directed into cooperation with the now multiply coated fabric X. This may be eifectedby layers toreceive a comparativelygether. As illustrated,,' this consists of, a doubling device E having a lower 1-0111 21 upon which the fabric X-Tests and a vertically adjustable up er roll 522 about and .under which the fabricY runs.- The double rolls 21 and 22 are of small diameter, and are adapted to exert upon the goods a comparatively light pressure, which effectually smears and distributes stance over the opposed faces of fabric without danger of forcing it through and defacing the outer surfaces. As the goods with the second coating leave proceed toward and through the doubler E, they are partially dried by some such means as steam coils 23 situated below their horizontal run, and are in better condition'to receive the pressure of a second doubling device F, the light rolls 24 and 25 which may be in all respects similar to and act in the same manner as the waterproof subpleted, and the bringing together of the layers of fabric carried as far as is possible without endangering the exposed surfaces. 3 After traversing the roll 26 which guides the goods 'through the light doubling devices, they are directed by idlers 27, 28 and 29 over the periphery of. a heating drum 30, contacting with a considerable portion thereof to attain the necessary evaporation of the solvent in the coating. A further drying effect is given by the action of the succeeding element G, which, as illustrated, is often termed a festooner. Overa horizontal series of small rolls or othersupports 31, the goods travel from the idler 29, falling therefrom in long parallel folds. Above the supports is a hood 32 connected with a conduit 33, through which an upward current of air is maintained by any suitableex haustmeans. In addition to acting as a drying means, the festooner furnishes a slack'portion in the goods whereby the capacity for free variation in the amount included in the folds compensates for difler-' encesin speed in the elements of the apparatus at its opposite sides. V

ponleaving the festooner, th'ei-coating substance has been reduced to a condition in which the layers of fabric may be safely brought into intimate contact. therefore,directed by rolls 34:, 35 to a doubling device H, provided with a large fixed.
